GARRY R. PERKINS ATTORNEY MAGAZINE CGNSTRIJC'IION FOR FASTENER DRIVING MIACIIINIE DESCRIPTION OF THE INVENTION This invention relates to a magazine construction for a fastener driving machine which is extremely inexpensive to manufacture. The magazine consists of a single formed member and can be made very inexpensively and automatically through a series of progessive dies. At the same time, the magazine is extremely rugged in construction because of its integral character and normally will not fail even under the most severe load requirements.

The invention may be briefly described as comprising an integral body having a support element and a parallel rail. A base portion joins the support element to the rail and a roof portion overlies the elements. A follower is slidably disposed upon the rail and is adapted to abut a series of fastener elements in laterally aligned relationship. Spring means are provided to forwardly bias the follower.

The invention will now be further described by reference to the accompanying drawings which are made a part of this specification.

FIG. I is a side view of the magazine of this invention a secured to a conventional fastening device.

FIG. 2 is a bottom plan view of the structure shown in FIG. I.

FIG. 10 is a bottom plan view of the mechanism of this invention with the fastener driving machine removed for clarity of illustration.

FIG. II is a cross-sectional view of the magazine shown in FIG. 8 taken along lines 11-I1 of FIG. 8.

FIG. 12 is a cross-sectional view of the magazine shown in FIG. 8, taken along lines 12-12 of FIG. 8.

FIG. 13 is a cross-sectional view of the magazine shown in FIG. 8, taken along lines 13-13 of FIG. 8.

FIG. 14 is a fragmentary detail side view of the follower and associated rail structure showing the position of the follower as it is drawn rearwardly and before it is retained in position.

FIG. I5 is a view similar to that of FIG. 14 but showing the retained position of the follower on the rail so that staples can be placed upon the rail.

A detailed description of this invention will now be given by reference to the specific form thereof as shown in the accompanying drawings. In this connection, however, the reader is cautioned to note that the specific form of this invention, as shown in the specification, is for illustrative purposes and for purposes of example only. Various changes and modifications can obviously be made within the spirit and scope of this invention.

Now referring to the specific form of this invention, as shown in the accompanying drawings, a fastener driving machine II is shown which includes a supporting frame 12 having a front portion I3 and a rear portion I4.

An air inlet 25 is provided to permit pressure air to selectively actuate a piston and a driver blade connected thereto which are not shown and are disposed within housing IS. The driving mechanism is not part of this invention and any type of such structure (which may be conventional) will suffice.

The magazine I6 is made of a single piece of metal as shown clearly in FIG. 7. It is formed into the: structure of this invention preferably by a series of progressive dies. The magazine 16 includes a longitudinal support portion I7 which is secured to front portion I3 of frame I2 by screws I8 and I9 (FIGS. 2 and 3). Screws I8 and 19 pass through openings 20 and 21 respectively (FIGS. 7 and I0) and respectively through a pair of threaded openings disposed within portion I3. One of these openings 22 is shown in FIG. 3. The magazine is further secured into position upon frame I2 by means of a pair of locating pins 23 and 24 which are carried by front portion I3 and pass through openings 26 and 27 provided within magazine 16.

A drive channel support member 28, which contains a channel for the driver blade, is secured to portion I3 and depends therefrom. Magazine 16 is also connected to member 28 by a pair of screws 29 and 30, which bear nuts 31 and 32 respectively and which pass through openings 33 and 34 in magazine I6 and aligned openings 35 and 36 within support 28.

Support portion I7 is also secured to rear portion 14 of frame 12 by screw 37 and 38 which pass through opening 40 and opening 41 located within frame I2 and support I7 (FIG. 6).

A rail 42 is disposed in parallel relationship with support I7 and is connected thereto by base portion 43. A roof portion 44 is also carried by support 17 and overlies rail 42 in spaced relationship thereto.

Rail 42 and the parallel support portion 17 are provided with matching cutout portion 45 at the rear thereof (FIG. I0). Portions 45 are inclined upwardly and reach their maximum upward position at 59. A follower 46 is slidably disposed along rail 42 and handle 48 includes a holding portion 47 and a manual handle 48. Follower 46 also includes an upper portion 4'3" which overlies rail 42 and a lower portion 50 which underlies rail 42.

A flat coiled spring 51 is disposed upon bobbin 52 which is secured to frame I2 by screw 19. One end of spring SI is secured to bobbin 52 and the opposite end 53 bears a recess 54 which accommodates holding portion 47 (FIG. 3).

With the foregoing specific description the operation of this invention will now be explained.

The magazine I6 is secured to the fastener driving machine II by the screws and nuts heretofore set forth. The follower 46 is disposed upon the rail 42 by normal assembly methods. The end 53 of spring SI is secured to holding portion 47.

The operation of this invention will now be explained. When fasteners are to be loaded into the machine the follower 46 is moved rearwardly in the direction of the arrow 57 in FIG. 1 by pulling on handle 48. Since handle 48 is offset this pull will cause an upwardly directed force to be exerted on the follower. As follower 46 reaches its rearmost position this force will cause the follower to move upwardly and, when the operator releases the pull on handle 418, will cause follower 46 to be retained against element 59.

Fasteners 55 (which can be nails, pins, staples, etc.) can then be disposed on the portion 56 of rail 42 as shown in the phantom lines in FIG. 1. The operator then will twist handle 48 and force it out of engagement with element 59. Spring 51 will then force follower 46 forwardly against the fasteners 55 into the position shown in the full lines in FIG. I and in the direction of the arrow 58. Follower 46 will then exert continuous pressure on fasteners 55 and will permit them to be sequentially driven by the driver blade of the machine.

The one-piece construction of the magazine of this inven- .tion permits severe jolting and forces of various types to be applied to the magazine without damaging the same. The construction is thus durable and rugged. Manufacturing, by means of a series of progressive dies, is cheap and simple.
